Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620344, here are decompositions:

43 + 31620301 = 31620344
193 + 31620151 = 31620344
277 + 31620067 = 31620344
307 + 31620037 = 31620344
331 + 31620013 = 31620344
433 + 31619911 = 31620344
523 + 31619821 = 31620344
631 + 31619713 = 31620344

Showing the first eight; more decompositions exist.
